Description

The present invention relates to a vehicle head-up display device and a control method thereof, and more particularly to a vehicle head-up display device including a combiner that provides an image and a shutter that protects the combiner, and a control method thereof.

In general, while the vehicle is traveling, the driver operates while confirming vehicle information such as the traveling speed of the vehicle, the rotational speed of the engine, and the fuel amount displayed on the instrument panel.

Since the instrument panel is located on the dashboard of the vehicle and the driver has to bow his head to check the vehicle information, the driver's line of sight deviates from the front and there is a danger of a safety accident.

In order to solve such a danger, a vehicle head-up display (HUD) device has been developed as a device that provides driver safety and effectively transmits vehicle information to the driver.

The vehicle head-up display device allows the information on the instrument panel to appear on the windshield in accordance with the driver's eyes so that the driver can easily check the vehicle information while driving.

Therefore, since the driver can check the vehicle information without changing the line of sight from the front while the vehicle is running, the driver can operate safely.

Vehicle head-up display devices can be broadly classified into a front window type that projects an image on a front window glass and a combiner type that projects an image on a separate combiner instead of the front window glass.

Compared to a front window type HUD, a combiner type HUD may be different in that it includes a shutter disposed in front to protect the combiner and includes a combiner and an operating device for driving the shutter.

However, the combiner type HUD is not a problem when travel-related information by the combiner is required, but when separate travel-related information is not necessary, the driver's attention is rather that a combiner exists in front of the driver. There is a possibility that a situation that disturbs the driving operation occurs.

Therefore, it is necessary to adjust the position of the combiner so that the combiner is positioned in front of the driver only when traveling-related information is required, and the virtual image seen by the driver is distorted in consideration of the driver's eyes. It is necessary to adjust the position of the combiner through raising and lowering and rotating the combiner so as not to occur.

The present invention provides an improved vehicle head-up display device in which a combiner is raised and lowered from a housing, and a shutter for protecting the combiner is opened and closed by sliding.
